Specification of Letters Patent. Patented july 11, 1911. Application filed March 13, 1911. Serial No. 614,171.

To all whom it may concern:

Be it known that I, WENDELIN P; SENG,-a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use of the bolt to, a common edge, andby forming a central concave 0r conical recess in the outer side, thus shaping aninclined zone aroundthe recess adapted to fit neatly in contact with the inner surface of the bed postcap; and by coating, as by dipping, the

head of the bolt with a metallic cement as a solder of lead and tin; whereby the zone of, contact thus formed has two edges to which the solder, when heated, will run, and form a fillet of the solder.

A preferred embodiment of the invention thus set forth in general terms, is illustrated in the accompanying drawings, forming part hereof, in 'which Figure 1 is a sectional view showing the bolt fixed in the cap and screwed into the bed post. Fig. 2, a detached perspective view of the bolt; Fig. 3, a detached elevation cave or convex recess 3 in its outer side, thusforming the inclined surface 4 around the shank on its inner side and the inclined contact zone 5 around the recess on its outer side, with theexternal annular edge that the periphery of the head and the internal annular edge 7 at the rim of the central recess. The head of the bolt thus shaped is then dipped into a metallic cement, as for-instance -a molten solder of tin and lead, so

that a coating of the solder will adhere to the head of the bolt; and the bolt thusm'ade is ready for being fixed in the cap of the bed 1 post, it being understood that the bolt heads are made in suitable sizes and proportions, and that the beveled contact zone is radially lnclined or curved to fit neatly against the corresponding portion 8 of the inner surface .of the bed post cap 9 to which the bolt is applied.

To fix the bolt in the cap, the cap is inverted as shown'in Fig. 4, and the bolt, having its head coated with solder, is inserted in the inverted cap, head downward, with the inclined zone 5 in contact with the, corresponding portion 8 of the inner surface of the cap, and with the shank of the bolt in the axial line thereof, as shown in the same figure. Heat is then applied to the under side of the inverted cap below the head of the bolt, to a suflicient extent to melt the solder thereon, whereupon the thin film of .the solder which coats the inclined contact zone will adhere to. the contiguous surface ofthe cap, and, more particularly, the solder -which is located on the inclined surface 4 forming the inner side of the head will run downward and outward and form a fillet as -10 around-the peripheral edge 6 of the contact zone, and the solder within the recess 3 in the outer side of the head of the bolt will likewise run downward and outward and form a fillet 11 around the interior edge 7 0f the contact zone; and when the heat is reand thatthe peculiar shape of the bolt set forth therein provides two edges, one on each sideof the contact- 'zone ofthe bolt head, to which a'substantial portion of the solder with which the bolt head has been coated will run and form a fillet, thus more securely joining the bolt to the cap than could bedone without employing the pecul iar shape of bolt head herein described; convexed on the outer and inner sides With a and it will be understood that the bolt, thus common peripheral edge, and having a censhaped and coated With solder, constitutes tral recess in the outer side forming a cona new article of manufacture which can be tact zone between the rim of the recess and 5 supplied to makers of beds and is adapted the peripheral edge, with a coating of solder 15 to be fixed in the metal cap of bed posts by a on the head.
